Abstract
The invention discloses a lithium battery which includes a cathode rod, an anode rod, electrolyte and a loading shell body, and as well as an electrolyte condensing liquefaction mechanism which is arranged above the liquid level of the electrolyte and includes a wire mesh pedal and a support, wherein the wire mesh pedal is arranged on the pedal and the pedal is installed on an inner wall of the loading shell body. The lithium battery can condense heated electrolyte vapor into electrolyte liquid and allows the electrolyte liquid to flow back to the electrolyte, thereby increasing utilization rate of the electrolyte. When the use time of the battery is increased, more and more gas is generated and also internal air pressure in the shell body is gradually increased too, so that for solving this problem, a user can know the air pressure in the shell body by an air pressure meter, and when the air pressure is too high, certain measures must be taken.
Description
Technical field
The invention belongs to lithium battery field, be specifically related to a kind of lithium battery.
Background technology
Along with scientific and technical development, in field of batteries, because lithium battery has that operating voltage is high, specific energy is high, long service life a little, progressively having replaced lead-acid battery, Ni-MH battery becomes the upper battery of society and uses the main flow of industry. But in the use procedure of lithium battery, ceaselessly in charge and discharge process, chemical reaction has occurred, produced unnecessary gas, and because flash-point and the boiling point of electrolyte are not high, electrolyte also can volatilize, and causes can existing in lithium battery the situation of lean solution. And reative cell internal gas pressure is excessive easily to be caused loading housing and expands, to the certain hidden danger of the security presence of battery itself.
Summary of the invention
In order to address the above problem, the invention provides a kind of lithium battery, concrete technical scheme is as follows:
A kind of lithium battery, comprise anode bar, cathode rod, electrolyte and load housing, also comprise electrolyte condensation liquefaction mechanism, more than described electrolyte condensation liquefaction mechanism is positioned at liquid level of electrolyte, described electrolyte condensation liquefaction mechanism comprises silk screen pedal and support, described silk screen pedal is rack-mount, and described support is arranged on the inwall that loads housing.
In use, especially in charging process, the reaction meeting heat release of reason, the temperature of electrolyte can raise, add that the flash-point of electrolyte own and boiling point are not high, be easily vaporized into gas, but after running into silk screen pedal, meet the cold electrolyte liquid that is liquefied as and again reflux back in electrolyte, so just can improve to greatest extent the utilization rate of electrolyte.
As further improvement, it is characterized in that: in described loading housing, be provided with three described electrolyte condensation liquefaction mechanisms.
Three condensing mechanisms are set, can improve gaseous state electrolyte solution and change into the yield of electrolytic liquid.
As further improvement, it is characterized in that: the upper inside wall of described loading housing is provided with barometer, described barometer is connected with outer application system.
Along with the continuous charging and discharging of lithium battery, the air pressure of object inside is increasing certainly, barometer is housed and can allows user understand at any time to load enclosure interior barometric information, does not exceed dangerous values and can allow user know for super, does certain prevention.
As further improvement, it is characterized in that: the top of described loading housing is provided with pore, described pore is provided with seal.
When housing internal gas pressure exceedes after certain value, can go special maintenance store to carry out exhaust, open seal, adopt vacuum absorption machine to absorb the gas in housing, and then can make the air pressure in housing get back to a normal value.
Otherwise air pressure is too high, may causes object to expand, and then affect the service life of battery.
Beneficial effect of the present invention: a kind of lithium battery provided by the invention, can allow the electrolyte steam being heated meet the cold electrolyte liquid that is liquefied as, be back in electrolyte, and then increase the utilization rate of electrolyte, along with the increase of service time of battery, the gas of generation increases, and the air pressure of enclosure interior also increases gradually, user can understand by barometer the air pressure situation of enclosure interior, need to take certain measure for the situation that air pressure is too high.

Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention is described in further detail, this embodiment, only for explaining the present invention, does not form and limits protection domain.
A kind of lithium battery, comprise anode bar 1, cathode rod 2, electrolyte 3 and loading housing 4, also comprise three electrolyte condensation liquefaction mechanisms, more than described electrolyte condensation liquefaction mechanism is positioned at liquid level of electrolyte, described electrolyte condensation liquefaction mechanism comprises silk screen pedal 5 and support 6, described silk screen pedal 5 is arranged on support 6, described support 6 is arranged on the inwall that loads housing 4, the upper inside wall of described loading housing 4 is provided with barometer 7, described barometer 7 is connected with outer application system, the top of described loading housing is provided with pore 8, described pore 8 is provided with seal.
In charge and discharge process, especially in charging process, exothermic heat of reaction, electrolyte is because flash-point is lower, be vaporized into gaseous state electrolyte, in the process rising, run into ground floor silk screen pedal, meet cold, most gaseous state electrolyte solution changes into liquid and is back in electrolyte, and small part gaseous state electrolyte continues to rise, and runs into second layer silk screen pedal, meeting cold liquefaction is back in electrolyte, remaining gaseous state electrolyte continues to rise and runs into the 3rd layer of silk screen pedal, meets in cold liquefaction backflow will electrolyte, and then has increased the utilization rate of electrolyte. And the electrolyte that liquefaction refluxes also can correspondingly share some gas flows, has reduced the pressure of gas, especially in charging process.
And along with service time of battery constantly increases, gas in housing will certainly increase, it is large that pressure can become gradually, this will make object dilatancy, and then cause the life-span of whole battery to be reduced, go out the air pressure situation of enclosure interior to customer responsiveness by barometer, for the too high situation of air pressure, user can go special specified point vacuum hytor to extract.
